This invention relates to a motor vehicle fan especially designed for efiecting a proper ventilation or stirring of the atmosphere about the occupants thereof, the fan being primarily designedfor use in the passenger compartment of closed cars: v I

On warm days, andeSpecially-whenthe motor vehicle has come to a stop for any reason whatsoever, the'heat within the car is 10 very noticeable, and more especially. when there is nobreeze' stirringfrom the outside. Again,,during the summer months when the atmosphere is quite humid, and especially during a heavy shower, the windows or panels of the vehicle become more orless steamed or have -a vapor condensed-- on the glass, by reason of the fact that the atmosphere with; in the car is not being stirred or'yproperly ventilated. I

The primary object of provide a motor vehicle fan which may be installed so as to fanthe air into the faces of the-passe ers, or tocreate a breeze about them for e 'ectively cooling them. A further object of the inventionis to provide a motor vehicle fan. having .a fluid pressure motor operative on a low-pressure such :as that invduced inthe intake manifold of the internal combustion. engine of such motor vehicle. T Another object of the invention :is to pro-- vide a fluid pressure motor of'the-suction.

operated type'which will not only stir air within the, vehicle, but will also remove the air! to a certainextent'so asto efiect a-more -35 or less continuous-changing of the atmosphere within the passenger compartment. I

The inventionfurther resides in the mounting of the an whereby it may be disposed in' an out-of-the-way position up against the ceiling of the car .when the fan is -not in use. In the accompanying drawings Fig.1 is'a fragmentary side-elevation of 'a motor vehicleof the closed car type; illustrating the application. of the present inventioni vFig. 2 is aside elevation of the'improved enlarged scale;

through one of the the installation of a modified type tion operated type, and comprisinga casing withinthe casing 1','a shaftejournaled in c casing and having the piston or vane fixed thereto, and an automatic valve mechanism for alternately connecting the opposite ends of the casing, or the casing on the opposite sides of the piston, to a source of operating pressure. The casing is provided witha suction passage 5 which is connected by a tube 6 I piston chamber to the respective sides of the piston 3 by a conduit 11. This valve chamber also has communication to the atmosphere throu h a passage 12, which is adapted to be close by. a sprin seated valve 13 which car r1es avalve 14 or closing the suction passage 9 when the valve 13 is unseated. Thus.

the valve device 13, 14, alternately opens its side of the casing, first to the source of suction or low pressure and then to the atmosphere. The means for operating the two valves consists of a rocker 15 having oppositely extending arms 16 underlying the stems 17 of the valves 13. This rocker also em arm 18 whic straddles the shaft 4 and is adapted to have its opposing furcations alternately enga ed by a in 19 fixed to a kicker plate 20, said icker p ate being pivoted on the shaft 4. A spring 21 connects a lateral pin 22 on the rocker member 15 to a lateral pin 23 on the kicker member so that the resulting action will be to effect a nick move ment of the kicker member 20 a r the pin asses a dead center position. An actuat ing'memben 24 is fixed on the shaft 4 to rock therewith, and as it rocks, said actuator will engage the pin 19 and start the movement' t of the kicker toward a osition in which the pin 23 will be ali ned with the pin 22 and the shaft 4, and as t e pin 23 moves beyond this v alignment, or dead center position, the potentialenergy of the tensioned spring 21 will qui ckl act to continue swinging'the kicker 20 an bring its pin 19 against the opposite furcation 18 to rock the member 15 and there'- by reverse the position of the two' sets of valves 13 and 14 so'that onevalve- 13 will be seated while. the other valve 13 ,is imseated, and a reverse relation of the valves 14. As the rockermember is rocked, one of its arms 16 is alternately moved past a retaining projection on a leaf spring 25 which, acts to yieldably lock the rocker in both of its positions. This valve actuation will alternately connect the two passages 11 to the source of suction, and the unconnected assage 11 will be in communication with ti de atmosphere, whereby the piston will be oscillated back and forth and effect a rocking of the shaft 4.

latter communication is obtained with the bodies an 11' wardly extending bifurcated- On the lower end of shaft 4 is mounted a fan of the leaf type, the same comprising a plurality of leaves 26 pivotally connected to the shaft whereby the leaves may be opened or closed,,the construction herein shown embodying a pivot bolt 27 about which the leaves pivot and a clamping nut 28 which may be adjusted to secure the leaves 26 at a desired adjustment. The full-line showing of Figs. 1 and 2 illustrates the fan element in this operative position, the angle of which maybe varied, and when it is desired to] discontinue the use of the fan, the leaves may be folded or collapsed and moved to an out-of-the-way position sych as isindicated by the dot and dash showing in Fig. 2. The fan is shown disposed in advance of the rear seat and may be folded or swung to one side to permit a ready entrance or exit from the car.

From the foregoing it will be noted that a novel-motor fan construction has been provided which is operated from the motor vehicle engine without subtraction from the power of the latter, and one which will gently waft the breezes over the occupants in the passenger compartment. Obviously, the fans may be distributed throughout the car and may be utilized to cool the occupant or oocupants of the front seat as well asthose of the rear seat. In Fig. 14 is shown another arrangement of fans which are disposed near the ceiling of the'car and to the rear of the back seat, the fans in this instance being of the rotary type and comprising a fan element 29 fixed to a shaft 30 of a'rotor or bladed piston 31. This rotor is disposed. within a casing 32 from which the air is exhausted through a conduit 33 which is in turn connected to the intake manifold, valve 34 being inserted in ms theconduit 33 ,to control the fan operation. On the opposite side-of the casing 32 from which the airis exhausted is a nozzle 35 which is designed to direct an inflowing current of air against the blades of the rotor so no that in this modification the atmosphere from within the car will also be exhausted through the motor.

In Figs. 16 and 17 are shown ventilatin fans similar to those depicted in Figs. 13 and 14 with the exception that they are reversed and designed to pull or force the air ,from within the car out through openings 36 providedin the walls of the vehicle. A similar type of rotary motor is employed to drive 1 s fan, which ma be so ported from the ceilingor the vehic e wall, y suitable brackets 37. In the modifications shown in Figs. 1417,'a more or less steady breeze is enerated about the passen ers so as to eect a constant agitation of t e atmosphere and a continuous renewin of the same by the ex haustion through the operating fan motor.

A motor vehicle fan for closed cars, comprising, in combination with the closed passenger compartment of a motor vehicle, a fan element arranged therein for effecting a change of atmosphere about the occupants, a suction operated, fluid pressure motor arranged within the passenger compartment for operating the fan element and having its inlet opening into said passenger compartment, and a suction passage between the motor and the internal combustion engine of the motor vehicle for having a low pressure induced therein by said engine whereby the atmosphere from within the passenger compartment will be drawn through said motor and efiect an operation of the same. W

2. A fluid pressure operated fan for the passenger compartment of a motor vehicle, comprising a fan element, a suction operated motor havmg a shaft directly supportin the fan element for agitating the air thereafiout,

3. In a fan construction for the passenger compartment of motor vehicles, a fan element,:a fluid pressure motor for operating the fan element to' agitate the air in the compartment, and means for directing a part of the air within the compartment through the motor to actuate the same whereby the air within the compartment will be both agitated by the fan element and exhausted by inoperative position 'ered to a position oppos te the occupants of a'breeze toward them.
